- Vacuum (spelled like so), means a complete lack of matter, or a device used for sucking up dirt or particles, or to use that device for cleaning.
- Vaccum and vacume are misspellings of vacuum.
Physicists often talk about vacuums, but the rest of us also use this word when talking about cleaning devices. Spelling the word can be a bit tricky because of the two consecutive u’s, which aren’t often seen in English.
